To find the time it will take for car A to overtake car B, we need to calculate the time it takes for car A to cover the distance of 12 km at the relative speed of 15 km/h (60 km/h - 45 km/h).
The time formula is distance divided by speed, so the time it takes for car A to cover the 12 km is 12 km / 15 km/h = 0.8 hours.
Converting 0.8 hours to minutes, 0.8 hours * 60 minutes/hour = 48 minutes.
Therefore, it will take 48 minutes for car A to overtake car B.
Two cars, A and B, are traveling at speed 60km/h and 45km/h respectively. If car A is 12km behind car B. Assuming they maintain the same speeds, how long will it take(in minutes) for car A to overtake car B?

Karabo drives the 60km between Johannesburg and Pretoria at a speed of 120km/h. Mpho drives the same distance at a speed of 100km/h. How much longer does Mpho take to arrive at his destiny?
To find out how much longer Mpho takes to arrive at his destination compared to Karabo, we need to calculate the time it takes for each of them to cover the 60 km distance.
The time formula is distance divided by speed.
For Karabo, the time taken is 60 km / 120 km/h = 0.5 hours.
For Mpho, the time taken is 60 km / 100 km/h = 0.6 hours.
To find out how much longer Mpho takes, we subtract the time taken by Karabo from the time taken by Mpho: 0.6 hours - 0.5 hours = 0.1 hours.
Converting 0.1 hours to minutes, 0.1 hours * 60 minutes/hour = 6 minutes.
Therefore, Mpho takes 6 minutes longer to arrive at his destination compared to Karabo.
The time formula is distance divided by speed.
For Karabo, the time taken is 60 km / 120 km/h = 0.5 hours.
For Mpho, the time taken is 60 km / 100 km/h = 0.6 hours.
To find out how much longer Mpho takes, we subtract the time taken by Karabo from the time taken by Mpho: 0.6 hours - 0.5 hours = 0.1 hours.
Converting 0.1 hours to minutes, 0.1 hours * 60 minutes/hour = 6 minutes.
Therefore, Mpho takes 6 minutes longer to arrive at his destination compared to Karabo.
