Question

a girl cycles for 3 hours at a speed of 40km/h what distance did she travel ?​

Answer 1

Step-by-step explanation:

To solve this problem, we’ll utilize the “time-speed-distance” relationship which is expressed by the formula d = rt, i.e., distance is equal to speed multiplied by time.

We’re given that the travel time is t = 3 hours and at a speed of r = 40 km/hr. Now, substitute the given value for t and the given value for r into the time-speed-distance formula and then solve for distance d as follows:

d = rt

d = (40 km/hr.)(3 hours)

= [40(3)] (km/hr.)hr. (You can treat units of measure just like you do

numbers, for example, you can cancel them)

d = 120 km is the distance the girl traveled on her bike.

Answer 2

Answer:

120km

Step-by-step explanation:

cycling speed of a girl = 40km/h

Time taken = 3 hours

Distance = Speed X time

= 40km/h X 3 hours

= 40 X 3

= 120

So,

The distance travelled by girl is 120km.
