A biker rode 45 miles in 180 minutes. What ws his speed (mph) during this ride ?
- A. 17 mph
- B. 17 mph
- C. 17 mph
- D. 17 mph
Answer: Option B
Explanation:
We know,
60 minutes = 1 hour
Or, 1 minutes = 1/60 hour
Or, 180 minutes = 180/60 hour
= 3 hours
Here, Times (t) = 3 hours;
Distance (s) = 45 miles
And Velocity (v) = ? Mph
Again, we know that,
S = vt
= > v = s/t
= > v = (45÷3) mph
= > v = 15 mph
