Question

5. Acar can finish a certain journey in 10 hours at the speed of 48 km/h. By her
should its speed be increased so that it may take only 8 hours to cover the
distance
​

Answer 1

Step-by-step explanation:

Time =10hr

speed =48 km/h

to find : distance =?

distance =speed x time

= 10 x 48 = 480 km

Acar takes 10hr to complete a distance of 480 km at speed of 48 km/h

time =8hr

distance =48 km

to find :speed = distance /time

=480/8 = 60 km/h

:. Acar took 8hr to complete a distance of 480 km at a speed of 60 km/h
