Igor and sally both tan the same distance. Igor completed The distance in two hours. His average speed was 6 mph. Sally completed the distance in four hours. What with Sally is average speed for the journey? Give your answer in miles per hour

Answer 1

Answer: 3mph

Step-by-step explanation:

Speed is calculated as Distance/Time.

Igor's distance = Speed × Time

= 6 × 2

= 12m

Since they ran same distance, Sally also ran 12m

Sally's speed = Distance/Time

where,

Distance = 12m

Time = 4 hours

Average speed = 12/4 = 3mph
