Answer:
30 mph
Step-by-step explanation:
First we need to find the distance travelled in the first 1h30m.
We can do that multiplying the speed by the time travelled, so we have:
Distance1 = 50 * 1.5 = 75 miles
If the total distance is 120 miles, Michael still needs to travel 120 - 75 = 45 miles.
And if the total time travelled is 3 hours (10 AM - 7 AM), the second part of the travel has a duration of 3h - 1.5h = 1.5h
So if the distance is 45 miles and the time is 1.5 hours, we can find the speed of the second part:
45 = speed * 1.5
speed = 45/1.5 = 30 mph
4382
Since 4.1% x 8 = 32.8%
32.8% of 3300 = 1082.4
3300 + 1082.4 = 4082 rounded
The answer is the middle one.
Yo sup??
total distance travelled by Janae =sum of distance on the 2 semicircles+ sum of the distances on the 2 track
=2πr+2*l
l=3 miles
r=1 mile
So,
total distance=2*3.14*1+2*3
=6.28+6
=12.28
=12.3 miles
Therefore the correct answer is option D
Hope this helps
