Answer:
3770 mm.
Step-by-step explanation:
The diameter of of the wheels is 60mm, that means the radius is 30mm.
Now for one revolution of the wheels, they cover the distance of 
on the ground.
For 20 revolutions, the distance covered will be 20 times this.
Thus
Which is our answer.

Answer:
length =29m width =11m
Step-by-step explanation:
length---L
width -----W
L=3W-4
area=319sqm
area of rectangle=L × W
area of rectangle =W ×(3W - 4)=319
expanding...
3W^2 - 4W=319
3W^2 - 4W -319=0
factorize
(W-11)(3W+29)=0
W=11 or -29/3
using the positive because the negative width with a minus sign does not make sense in real life, we use 11m
width =11m
length 3W -4=3(11) -4 =29m
The ratio is 1:20 so if you need to go up 2.5 inches you need to travel 2.5x20 inches horizontally.
2.5x20=50 inches.
