Question

A car travels 60 km in 1 hr How long will it take to cover a distance of
100 km at the same speed?
found to vary directly with the weight​

Answer 1

Answer:

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}}Speed=

Time

Distance

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

If the distance = 100 km,

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

Speed

Distance

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

40

100

= 2.5 hours or 2 hours 30 minutes
