Question

A bus takes 48 minutes to cover a certain distance when travelling at a speed of 50 km/gr8. How much time will it take to cover the same distance when travelling at a speed of 30 km/n't?

Answer 1

Answer:

The bus will take 80 min

Step-by-step explanation:

48min=48×60sec=2880sec

Since Distance=Speed×Time

So,

According to first condition,

D=S×T

D=50m/s×2880s

D=144000m. ...(I)

According to second condition,

D=S×T

144000m=30m/s×T ...(From I)

T=144000m/30m/s

T=4800s

4800s=4800/60min=80min

ANSWER:-80min=1hr,20min
