300 miles in 1h 40m
300 miles in 100m
300 / 100 = 3
3 miles per minute
3 x 60 = 180
180 miles per hour
I hope this helps
139 is suppose to be 140 and 18 is suppose to be 20, 140 x 20 = 2800
Home this works
1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 6/3
Answer:
18.288
Step-by-step explanation:
Answer:
a. The constant = 45
b. The unit rate is 45 miles per hour
c. d = 45t
Step-by-step explanation:
a. ∵ d ∝ t
∴ d = kt
∵ d = 90 at t = 2
∴ 90 = k(2)
∴ k = 90 ÷ 2 = 45
∴ The constant of proportionality is 45
b. ∵ k = d(miles) ÷ t(hours) = 45
∴ The unit rate is 45 miles per hour
c. The equation is ⇒ d = 45t
