A) \[\frac{5hi}{m}\]
B) \[\frac{60hi}{m}\]
C) \[\frac{hi}{12m}\]
D) \[\frac{5m}{hi}\]
Correct Answer: A
Solution :
The turtle moves /; inches in W minutes. We are asked to find out how many feet will it move in \[h\] hours. Here, we will have to convert feet in to inches and hours into minutes. Let \[x\] be the distance in feet covered by the turtle. Feet \[=12\times \] inches Also, \[h\] hours \[=60h\] minutes. To find out the distance travelled by the turtle, we need to form proportions. \[\therefore \] \[\frac{i}{m}=\frac{12x}{60h}\] \[\Rightarrow \] \[x=\frac{60h.i}{12m}=\frac{5h.i}{m}\]
