Question

what is the speed of a bus if it travels 54km in 90 min

Answer 1

Answer:

Answer. Speed = distance / time = 54 km / (3/2) hr = 54*2 / 3 = 18*2 = 36kmph . A bus travels 54 km in 90 minutes. the speed of the bus is 36 kmph.

Answer 2

$Given: \\ distance=54 \: kms \\t=90mins \implies1hr=60min \\ 1min= \frac{1}{60} hr \\t= \frac{90}{60} =1.5hr \\Speed= \frac{distance}{time} \\= \frac{54}{1.5} =36 \: Km/hr \\ 1km/hr= \frac{5}{18} m/s \\ speed=36 \times \frac{5}{18} =2 \times 5=10m/s$
