Question

Q. A bus takes 1 hr 30 minutes to cover a certain distance at a speed of 60km/hr. How much time will it take to cover the same distance when traveling at a speed of 45km/hr? ​

Answer 1

STEP 1

d = s × t { 1h-60mins. 60mins.-1h }

{ 1min.-1/60h 30mins.-½h }

d = 60 × 1½

d = 30km

STEP 2

t = d / s

t = 30/45

t = 2/3

T = 2 / 3 h
