Answer:
8mph
Step-by-step explanation:
when dina arrived to 20 masha was at 16. so the relation is 20/16 and if dina's speed was 10 your formula is 10/x=20/16 that means x/10=16/20. so x will be 8
The required Masha's biking speed is x = 8mph
Given that,
Dina and Masha started out on a 20 miles bike path at the same time. When Dina reached the end of the 20 miles,
Masha still had 4 miles left to bike. If Dina's biking speed was 10 mph.
We have to find,
Masha's biking speed.
According to the question,
Dina and Masha started out on a 20 miles bike path at the same time.
When Dina reached the end of the 20 miles, Masha still had 4 miles left to bike. If Dina's biking speed was 10 mph
When Dina arrived to 20 Masha was at = 20miles - 4miles = 16miles.
Therefore,
The relation is 20\16 and if Dina's x speed was 10 in the formula is,
The Masha's biking speed is,
[tex]\dfrac{20}{16} = \dfrac{10}{x}\\\\20x = 10\times 16 \\\\20x = 160 \\\\x = \dfrac{160}{20}\\\\x = 8[/tex]
Hence, The required Masha's biking speed is x = 8mph
