Answer:

Bryce's speed (slow speed I might add) is   3 miles per hour.

Explanation:

s /d= t

where  

s = speed  d= distance  t  = time.

Solving for   gives:


s = 1/3 / 1/9

s= 9/3

s= 3 miles per hour

How would you write 87 as a Roman numeral?
ddd [48]

Answer:

LXXXVII

Step-by-step explanation:

L=50 X=10 V=5 I=1

So basically you need to figure out what adds up to the 87. so use L, or 50. now XXX=30. so now you have 80 so we still have 7 left over, so we can write 7 I's or a 5, (V) and two I's. We should use the V and the I. So we take one V, or 5. and two I's which together is 7. which leads us too LXXXVII. also always remember to have the biggest number first, in this case the L (50).
