Answer (A) ⇒ How many 3/8 's in 48
Step-by-step explanation:
∵ The distance = 25 miles
∵ The time = 2/3 hour
∵ Average speed = distance ÷ time
∴ Average speed = 25 ÷ 2/3 ⇒ step 1 (he is √)
= 25 × 3/2 ⇒ step 2 (his 1st error 1/25 × 2/3)
= 75/2 miles/h
∵ How many 3/8 's are in 48 means:
48 ÷ 3/8 = 48 × 8/3 = 128
∴ Answer (A) is best modeled with a division expression
