Problema Solution
A toy company is making a miniature model of a dump truck. The steering wheel on the toy car that is 0.6 cm corresponds to the steering wheel on the real truck that is 55.2 cm. A windshield on the toy car that is 3.5 cm corresponds to the windshield on the real truck that is x cm.
If the unit rate remains the same, what is the value of x?
Answer provided by our tutors
0.6 : 55.2 = 3.5 : x
we cross-multiply
0.6x = 55.2*3.5
x = 55.2*3.5/0.6
x = 322 cm
3.5 cm windshield on the toy car corresponds to the 322 cm windshield on the real truck.
