Mai and Priya were on scooters. Mai traveled 15 meters in 6 seconds. Priya travels 22 meters in 10 seconds.

1. Who was moving faster?

2. Explain your reasoning.

priya was going faster

Step-by-step explanation:

she was going faster in a longer period of time and at a constant rate of 22 meters every 10 seconds. While mai was only going 30 for every 12 which makes it equal to 26.4 for priya

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
