Question

a bus travel 18 miles in 90 mine how far it travel in 21 mine

Answer 1

Answer:

4.2 miles a bus can travel in 21 minutes

Step-by-step explanation:

distance =18 miles

time = 90 minutes

speed = distance/ time

          = 18miles/90 minutes

           =  0.2 miles/ minutes

Now, time is given 21 minutes, speed = 0.2 miles/ minutes

here we find distance:   Distance = speed x time

                                                      = 0.2 x 21

                                                     = 4.2 miles
