Question

A bus A travelling at speed of 70 kilometre per hour just over takes another bus B at a speed of 60 km per hour. The length of each bus is 10 metre. Calculate the time taken by the bus A to overtake bus B

Answer 1

Answer:

given that

speed of bus A=70km/hr

do we of bus B=60km/hr

the length of the bus is 10m

then d=s/t

then t=d/s

let the time be x

then x=20m/70km/hr

(distance = to come in side by did ..1

to overtake ...2

=1+2=10+10=20m)

=0.285sec

$20 \div 70$

Answer 2

Answer:

given that

speed of bus A=70km/hr

do we of bus B=60km/hr

the length of the bus is 10m

then x=20m/70km/hr

(distance = to come in side by did ..1

to overtake ...2

=1+2=10+10=20m)

=0.285sec

20 \div 7020÷70
