Answer: 15 mph
Step-by-step explanation:
Given: Time taken to travel uphill to the toy store= 12 minutes
Let d be the distance(in miles) between the home and toy store.
Also,
Thus, distance from home to toy store= 2 miles
When she turn back, to home distance remains same.
The time taken by her to come back at 30 mph speed=
Now, the average speed =
The large triangle and the smaller one are similar. Comparing long sides to short ones, we get
.. (30 mm)/(21 mm) = (14 mm +x)/(14 mm)
.. (14 mm)*10/7 = 14 mm +x
.. (14 mm)*(10/7 -1) = x
.. (14 mm)*(3/7) = x = 6 mm
The value of x is 6 mm.
