Answer:
1½ mile
Step-by-step explanation:
Given
3/10 mile = ⅕ hour
Required
Determine the distance in 1 hour
Since rate is constant, we have:
3/10 mile = ⅕ hour
Multiply both sides by 5
5 * 3/10 mile = ⅕ hour * 5
15/10 mile = 5/5 hour
3/2 mile = 1 hour
1½ mile = 1 hour
Hence,the child will walk 1½ mile in 1 hour
If we work it through:
70mph is 11mph less than 3 times the fastest running speed for a man.
So 70 + 11 = 81mph is 3 times the fastest running speed for a man.
Can you see where to go from here?
No that’s equivalent to 7 + 7x
