Question

an object moves at 10 km per hour for 10 minute and then move 15 km per hour for 15 minutes find the total distance travelled by the object

Answer 1

Convert minutes to hours:

10 minutes=0.17 hours

15 minutes=0.25 hours

using, distance=speedxtime

distance=10x0.17

                    =1.7 km

 distance=speedxtime

                  =15x0.25

                  =3.75 km

 Total distance=3.75+1.70

                              =5.45 km
