Question

a car travels 245km at a constant speed of 3.5hours. how far does it travel in 90 minutes

Answer 1

Distance varies directly with time, that is, the longer you drive the farther you go
So we can use a simple ratio.

245/3.5 = x/1.5
3.5x = 1.5(245)
solve for x

Answer 2

r = 245/3.5 = km/h.
t = 90min. = 1.5 h.
d = r * t =

Answer 3

for 245km= 3hrs 30mins.

Let x be the distance traveled within 90mins.
1hr 30mins ×245km=3hrs 30minsx

Hence solving the equation we have x to be 105km.

Answer 4

Therefore, the car travels a distance of 105 km in 90 minutes.
