Imani and Abedi drive to work. Imani drives 66 miles in 1.5 hours.
Abedi drives 56 km in 1 hour 15 min.
Work out the difference between their average speeds in km/h.
1 mile = 1.6 km

correct answer:

a + bi

110

step-by-step explanation:

based on the question i am guessing that it is a typo for abc

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
