A CAR TRAVELS 60KM IN 1HR 30MIN.HOW LONG WILL IT TAKE TO COVER A DISTANCE OF 100KM AT THE SAME SPEED.

use ratios:

60 km / 1.5 hours = 100 km /x hours

x=1.5 hours * (100/60) = ?

18 sec

2 hr 30 min

Its direct variation.

1 hr 30 mins = 1.5 hrs
60 km /1.5 hours = 100 km /x hours
x = 1.5*(100/60)=2.5 hours
So,2.5 hours = 2 hours 30 mins

Let the Required time be t

As it is direct variation.

60/1.5=100/t

T=2.5 hours or 2 hrs 30 mins

To find out how long it will take to cover a distance of 100 km at the same speed, we can use the formula:

Time = Distance / Speed

Given that the car travels 60 km in 1 hour and 30 minutes, we need to convert the time to hours.

1 hour = 60 minutes

So, 1 hour 30 minutes = 1.5 hours

Now, let's substitute the values into the formula:

Time = 100 km / 60 km/h

Simplifying the equation:

Time = 1.67 hours

Therefore, it will take approximately 1 hour and 40 minutes to cover a distance of 100 km at the same speed.
