Hint: To find the average speed for the car to cover the distance of 5 km, we will divide the value of the distance by that of the time travelled, now to find the velocity in terms of km/hr
, we need to convert the time from minute to hour by dividing it by 60 and the formula for the speed is:
Speed = DistanceTime
Complete step by step answer:
The distance travelled by the car in km is given as 5 km
.
The time taken to cover the distance of 5 km
is 5 min
.
Now to convert the time from minute to hour is given by dividing the minute value by 60
. Hence, the minute value is:
⇒560=112h
Now using the time, distance and speed formula, we find the value of the speed in terms of km/hr as:
Speed = DistanceTime
Placing the value of distance and time in the above formula, we get the value of the speed as:
⇒Speed = 5 km112hr
∴Speed = 60 km/hr
Therefore, the value of the speed of the car moving a distance of 5 km is given as 60 km/hr
.
Note:
Another method to find the speed is by converting the distance from 5km
to 5000m
and time from minute to seconds as 5min
to 5×60=300 seconds
, then using the formula of the speed and its value as:
Speed = DistanceTime
Placing the value of distance and time as 5000m
and 5min
respectively. The value of the speed in terms of m/sec
is:
Speed = 5000300
⇒Speed = 5000300 m/s
Now to find the speed in terms of km/h
from m/s
, we will multiply the speed by 185
to get the speed in terms of km/h
unit.
⇒Speed = 5000300×185
⇒Speed = 60 km/hr
