He goes 50 mph for 200 miles, meaning he travels 200/50 = 4 hours.
He then goes 40 mph for 100 miles, meaning he travels 100/40 = 2.5 hours.
So, he travels 300 miles in 6.5 hours, meaning he goes 300/6.5 = 46.1538 mph.
Step-by-step explanation:
10 × n = 360
n = 360 ÷ 10
n = 36
So, n = 36
(3 × 4) × 5 = k × (5 × 4)
12 × 5 = k × 20
60 = k × 20
k = 60 ÷ 20
k = 3
So, k = 3
