Question

a car travels 60 km in 1 hour 30 minute how long will it take to cover a distance of 100 KM at the same speed

Answer 1

time taken to cover 60 km=60+30=90 min.

now time taken to cover 1km=90/60=3/2 min

therefore time taken to cover 100km =100x3/2=150 min or 2 hours 30min

Answer 2

Answer:

2 hours 30 minutes.

Step-by-step explanation:

Given,

The total distance = 60 km,

Time, t = 1 hours 30 minutes = 1.5 hours,

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

So, the speed of the car = 60/1.5 = 40 km/h,

If the distance = 100 km,

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

Thus, the time taken by car = $\frac{100}{40}$

= 2.5 hours or 2 hours 30 minutes.
