Answer:

71 times

Step-by-step explanation:

Diameter of BMX bike= 0.45m

Radius= 0.225m

Cirumference of BMX bike

C= 2πr

C=2*3.142*0.225

C= 1.4139m

In a 400-m race, the BMX bike will turn

=400/1.4139

=282.9 times

=283 times

Diameter of Mountain bike= 0.6m

Radius= 0.3m

Circumference of Mountain bike

C= 2πr

C=2*3.142*0.3

C=1.8852m

In a 400-m race, the Mountain bike will turn

=400/1.8852

=212.17 times

=212 times

Hence the difference is

=283 -212

=71 times
