Answer: Crayfish, 25 s
Step-by-step explanation:
Given
The length of race is 60 cm
Flicker gets a 10 cm head-start
Cray fish covers 6 cm in 5 s i.e. its speed is

Flicker covers 4 cm in 5 s, its speed is

Time taken by Cray fish to cover the race is

Time taken by flicker to cover race with 10 cm head start

Time taken by crayfish is less. Hence, crayfish wins the race
When they both covers the same distance, they tied momentarily i.e.

After 25 s, they tied the race.
Answer:
-a+11
Step-by-step explanation:
hard to explain. but should be correct
M5 minus M6 will get M1
So 62 - 38 = 24
24 x 3 = 72
So M3 is 72

Now multiple the coefficients and add the exponents with common bases

Now write your final expression
